Abstract: A map-matching approach is presented that combines public bus routes information (sequences of consecutive stop locations and sequences of geo-referenced points) with a high resolution network. It is especially designed to account for a) low temporal resolution of geo-referenced points and b) to allow that a stop which is served by several lines is attached to one single link only. Taking into account fixed link-stop relationships and other parameters an automatic solution using the A * search algorithm between consecutive stops is generated for each route. The link cost takes not only the travel time into account but also the distance to the geo-referenced points. For final corrections, the approach includes a user interface which allows visualizing and modifying the network and the sequences interactively. It is possible to add or remove links, replace link-stop relationships, and review the correctness of the result. The effectiveness of the approach is reported.
